摘　　要：窃电行为不仅造成了国家电力的损失,在配电网中形成潜在的安全隐患,还为工作人员增加了工作难度。为探索高效可行的反窃电技术,采用前推回代法计算配电网电路潮流,得到线路损失值,确定疑似窃电位置。进一步计算电压偏移率和关联度,准确判定窃电点,并计算补足功率与实际功率差值得出窃电量。验证表明,该方法的潮流计算效率提高了30%左右。对高低压用户用电量实例分析时,共发现3个窃电点,电压关联度平均值在0.35左右,比正常关联度值低,证实了前推回代法在反窃电技术中的有效性,为电力系统反窃电工作的实施提供了合理参考。Electricity theft not only results in national revenue losses and potential safety hazards within the distribution network but also complicates the tasks for power personnel.In order to explore efficient and variable anti-electricity theft technologies,this research employs the forward and backward substitution method to calculate the power flow within the distribution network circuit.This method enables the determination of line loss values and identification of suspected electricity theft locations.Furthermore,it calculates the voltage offset rate and correlation degree to accurately pinpoint instances of electricity theft,assessing the variance between supplemental and actual power to qualify stolen electricity.Through experiments and case studies,a notable enhancement of approximately 30%in the efficiency of power flow calculation using this method has been demonstrated.Analysis of electricity consumption examples among high and low voltage users revealed three instances of electricity theft,with an average voltage correlation value of approximately 0.35,indicating deviation from the normal correlation value.These findings validate the efficacy of the forward and backward substitution method in anti-theft technology,providing a valuable insights for the implementation of anti-theft measures within the power system.
